bitx20 v3 build – bandpass filter

Published April 16, 2017

The bandpass filter for the bitx is now complete. While I’ve been building the bitx, I’ve been checking other build logs as I go along. One that has been helpful is PA1ED’s deadbug style bitx build. I decided to build the same bandpass filter that he used which is actually from version 1 of the bitx. You can find more info here.

Here is the whole layout as of now. I slapped together a simple 20 meter dipole and strung it from my front porch out to a tree. Its about 8 feet above the ground and doesn’t work very well, but I am able to pick up a few CW stations.
